How to make the non-main page of the site open when opened on a smartphone or tablet?

How to make it not open the main page of the site when opened on a smartphone or tablet?
Is it possible to implement this through html meta tags
I'm trying to do JS
var w=$('document').width();
if(w<=750){
window.location.href="/products/";
}
the transition occurs, but the problem is that the page starts to reload, I suspect due to pagination.

Answer 1

1) Override class and stub method with override

protected:
    void wheelEvent(QWheelEvent * event){}

2) Do the same with eventFilter

Answer 2

I think that you need to determine from the beginning what devices came from and then redirect to the desired page.

function isMobileDevice() {
  return /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent);
}
if(isMobileDevice()) {
window.location.replace("http://....com/products/");
или
window.location.href = "http://....com/products/";
}

Something like this)
